A WiMAX wireless network integrated with a satellite network can provide connectivity to any location within 10 km of the base station. The number of sectors per base station can be varied to increase the bandwidth. An independent cable operator is considering three bandwidth alternatives 44 (Mbps), 55 (Mbps), and 88 (Mbps). Assume a life of 20 years and a MARR of 10% per year. Operating Annual Bandwidth, First Cost, Cost, Income, Mbps $1000 $1000 per Year $1000 per Year 44 -40,000 -2000 +5000 55 - 46,000 -1000 +5000 88 -61,000 -500 +8000 1- Use incremental RoR analysis (IRR) and PW to determine the financially justified one. 2- Why should you use incremental Rate of return and what is the difference between that and MARR
